1 '0 all whom it may concern:

Be it known that I, OLor F ROBERG, a citizen of the United States,residing at Benton Harbor, in the county of Berrien and State ofMichigan, have invented certain new and useful Improvements in Gollarand Cuff Starching Machines, of which the following is a specification.

This invention has -for its object to effect improvements in collar andcuff starchlng machines calculated toimprove the quality of work turnedout thereby, to simplify the manipulations involved in the operation ofsuch machines, as well as manual operations involved in adjustment,cleanin and care of the machines and to cheapen the manufacture of themachines. I

It is an important aim to improve upon a number of details in machinessuch as illustrated in my prior patent issued October 26th, 1915, Number1,158,040.

In said prior machine, the feed throat was of such character that dangerwas involved for the operator of catching the fingers between the feedroller and the large platen roller 22-, in addition to which quite rapidWork and more sustained attention to the work after initial adjustmentthereof upon the conveyer web was required than is involved in mymachine, wherein the arrangement of the web is such that emplacement ofthe Work for feeding to the machine may be accomplished at aconsiderable distance from the throat space, and much less attention andmanipulation of the work in feeding is required. This enables the use ofa wider web if desired, or a more rapid movement of the machine, wherebyits output may be greatly increased without the necessity for additionaloperative labor.

In my prior machine, in the passage of the work from the main conveyerto the transverse delivering conve er, the work was considerablydisordered, and at times pieces tangled together, in the space betweenthe inverted reach of the web 42 and the transverse conveyor,necessitating con siderable work on the part of the operatorssubsequently in straightening out the pieces and arranging them inorderly fashion, so that they could be conveniently handled,

and would not have wrinkles therein when fed to the ironing machine.

In my present device, I have made certain changes which whilenotinvolving radically new structural features have been such as toproduce a marked change in the character of the work, eliminating thenecessity for the hand labor previously required in ordering the piecesand flattening the work prior to the ironing, as mentioned.

In the first machine, also, a roller 85 was located at the inner side ofthe large platen roller, adapted to bear thereagainst or against theinterposed web and work so as to remove the surplus starch from the workpassing between the rollers, an adjustment being provided for the rollerwhereby proper pressure would be exerted for the removal of the properquantity of the starch. The small roller was carried upon an adjustableframe by which certain other rollers were also adjusted with relation tothe platen roller, these other rollers being provided to work the starchinto the fabric while passing through the machine, before reaching theroller 85, by which the surplus starch was removed. In the prior machinethe adjustment of the movable frame. for proper positioning of thestarch working rollers would destroy the adjustment of the roller 85,and require a new manipulation of the adjusting means therefor. In mypresent invention the movable frame is ad justed as desired for securingthe proper action. from the starch working rollers, without destroyingthe adjustment of the means whereby surplus starch is removed, (whichmeans I term finishing rollers,) these be ing carried upon the device insuch a way as not to be interfered with by the adjustmentof the movableframe, while yet being carried thereon. s

The construction of the finishing means has also been greatly simplifiedand cheapened, and the mounting and construction of the movable framingfor the working rollers also simplified and improved.

My machine also embodies an improved means for lifting out the platenroller quickly to enable the removal of pieces which may have beenimproperly fed thereto; before they have passed completely through themachine, or for other purposes. This device also includes a novel anddesirable means for securing the platen roller releasably in operativeposition in an effective and satisfactory manner.

Additional objects, advantages and features of invention will appear inthe invention, involved in the construction, arrangement and combinationof parts, one of the possible emoodiments of which are set forth in thefollowing description, and shown in the drawings in the application, inWhich,

Figure 1 is a side elevation of the machine,

Fig. 2 is a front elevation thereof,

Fig. 3 is an elevation of the right hand side of the machine,

Fig. e is a detail of the clearing device at the discharge end of themain conveyer.

Fig. 5 is an enlarged detail of the finishing device,

There is illustrated a starch pan 10, sup portd by a suitable stand orframe work 11, which may he of any suitable kind. The pan has graduallyslopi bottom portions at the front and rear parts, the bottom preferablysloping more adually at the front part, so that the pan is quite wide atthe top. Pivoted adjacent the forward side of the supporting frame 11 ateach end, there are levers 12, of the class, having outer ends projectedhe and the frame and connected by a transverse bar 13, by which they areheld in a common plane. At their inner ends, the levers 12 carry hearingblocks 1-12, extending inwardly, the upper edge portion of the frame 11being suitably recessed to form a rest for these blocks when at thelower limit of their movement, but leaving them free for upward movementunder oscillation of the levers will be described. Upon these blocks 1there are revoluhly secured the trunnions 15 of a large platen roller16, the uses of which will be subsequently apparent. A. foot treadle 17is pivoted in a convenient position upon the lower part of the frame 11from which a link'18 is extended to the central part of the cross bar13, so that the levers 12 may be operated by the treadle to lift theroller 16 from it normal position. A stop rod 19 is also carried by thecross bar 13, having its lower end so positioned as to strike againstthe frame 11 to limit upward movement of the roller 16 in a propermanner.

The upper edge portion of the frame is formed vith an overhanging flange20, and pivoted upon the lever 12 at one side, or at each if desired,being so illustrated in the present instance, there is a locking lever21,

oscillrble in a plane transversely of the lever 12. In normal pos tion,the lever 21 extends at its inner part closely over the lever 12, and isformed with an inward extension adapted to engage under the flange 20when at the inner limit of its movement, so as to prevent lifting of thelever 12 at its inner part. T his extension also rests upon the upperside of the lever 12. The outer end of the lever 21 is provided with ahandle portion 23, for its manipulation, and a suitable spring 24; isprovided on the side of the lever 21 bearing against the lever 12 uponits outer side, so as to hold the lever 21 in looking position.

Secured on the upper part of the frame 10 at each side immediately infront of the roller 16 there are hanger arms 25, extending downwardlywithin the pan 11, and heing inclined slightly toward the rear at theirlower part, so as to lie closely under the roller 16 at a proper level.The lower ends of these hangers are formed with hook portions 27,receiving the projecting end portions of a transverse rod 28, carried ina roller frame 29, which comprises two similarly shaped elements 30,each having a curved lower part adapted to lie in parallel relation tothe periphery of the roller 16, and having a plurality of lots 31therein opening upon the inner edges of the members 30, in which are setthe trunnions of starch working rollers adapted to be adjusted in closebearing upon the roller 16 by movement of the rear part of the frame 29upwardly. The side members 30 are each provided with a rearmirdextension 3 1, extending approximately in a horizontal direction whenthe frame is in normal position. At the upper forward part of theextension in each case, a slot is formed, opening on the upper edge ofthe extension, and extending slightly in a forward direction toward itslower part, forming a bearing for the trunnions of an expressing roller36 of a site to lie spaced a distance from the roller 16 when in normalposition, as shown. The outer part of the extension 34: is bifurcated toform parallel guide arms, between which a sliding bearing 36 is mounted,carrying revoluhly one end of an expressing roller 37, for movement tobear against the roller 35, and for adjustment as desired. Across theouter end of the extension a cross piece 38 is mounted, in which thereis revoluhly engaged at hand screw 39 threaded in suitable manner in thebearing 36, whereby the latter may be adjusted longitudinally in theextension 31 Set in a lateral enlargement of the extension at each sidethere is a suitable screw 42 hearing upon the frame 10. The screw may berotated to adjust the frame 29 with relation to the roller 16. At theforward part of the machine, diagonal slide hearings llare mounted ateach side on the upper edge of the frame 10, inclined forwardly towardtheir upper part,

The upper end of the arm 25 is extended slightly above the upper edge ofthe frame 10, and slotted to form an open bearing 17, in which istrunnioned the roller 48-, some distance forwardly of the roller 16. Thelast mentioned roller and the roller 45 are nearly on the same level,although in adjustment of the roller 45 some change in their relativelevel may occur.

Upon the upper side of the tween the rests for the blocks '14 and therear side of the frame 29, suitable standards 50 are provided, inclinedslightly toward the rear and carrying at their extreme upper part avertically movable spring supported bearing block 51, having an openslot in the upper side in which rests the trunnions of a web roller 52.At a lowerposition on the standards nearly or quite over the roller 36 asimilar roller 53 is mounted, extending between the standards 50, whileabove this roller and spaced a short distance forwardly thereof anothersimilar roller 54 is mounted between the standards. The standards areformed with horizontal forwardly extending arms 55, upon the upper sideof which there is provided an inclined planiform guide 56, at each sidehav ing a central slot therein, through which projects an arm 57 of aslide bearing 58 mounted onethe guide, this bearing having a,

slot formed therein inclined upwardly and forwardly, and being open forthe reception of the trunnions of an adjustable web roller 59, so thattheroller may be lifted out of the bearing at times without the removalof any nuts, bolts or other bearing parts. An endless web 60 of asuitable material is mounted so as to circulate upon the rollersdescribed, forming a conveyer. This web may be said to have an outerportion forming the return part of the eonveyer, and an inner portionserving as the work carrying part. The outer portion extends over theroller 59, over the roller 52 and downwardly therebeside, to the roller37, upon the outer side of which it rests, passing downwardly therefromand under all of the-rollers 32, r

from the most forwardly of which the web extends to the roller 45,beneath which it passes, thence upwardly and over it ina rcarwardlydirection to the roller 48, for1ning a table reach at the beginning ofthe inner part of the conveyer, passing then over the roller 48 anddownwardly convergently to the periphery of the roller .16, againstwhich it engages a distance belowthe top of the frame 10, although thisparticular relation is not essential, though it is desirable that theweb should be slightly inclined before it engages the last mentionedroller.

frame 10 bei From the underside of the roller 16 the in ner section ofthe web 60 passes between the rollers 36' and 37, thence upwardlyrearwardly of and over the rollers 53 and 5 1 forming therebetween anoblique reach, and thence forwardly at an acute inclination with respectto the horizontal, to the underside of the roller 59', forming in thislast portion what is termed an inverted reach 61. luiding tapes 62 are;engaged around the roller 16, being extended upwardly and rcanmrdlytherefrom between the rollers 36 and 37 in close relation to the innerportion of the web 60, and extending also upwardly and forwardly aroundthe roller 53, from which thei tapes return to the roller 16.

lWIounted upon the forward side of the being adjustable in the samemanner as the rollers l5'and37 before described.

Upon the standard 50 at the right hand side of the machine a. bearing 65is provided, and upon the outer end of the arm 50 carried by thisstandard a bearing 65 is provided upon a suitable bracket 66, these twobearingssupporting a horizontal roller 67 extending longitudinally ofthe machine. At the opposite side, upon the standard 50 and a bracket 67at the outer end of the arm 50, slide bearings 68 are provided, carryinga roller 69, in a manner similar to the mounting of the rollers 15' and38 before mentioned, whereby it may be adjusted horizontally to theright or to the left. Around the rollers 67 and 69 an endless crossapron 0r conveyer- 70 is mounted, adapted to receive work passing overthe roller 54 and falling from the inverted reach of the web 61. Aclearing knife 71 is mounted'between shaft. The gear 72 may be driven byany well known power connection, as shown at 7 3, or otherwise; Theshaft 74 of the roller 53 is also extended beyond the righthand side ofthe frame, and provided at its outer part with a sprocket 7 5, andinwardly of the sprocket a beveled gear 76. This last men tioned rolleris'on' a level with the roller 67 0f the cross apron, and the shaft ofthe last mentioned roller is extended and provided with a beveled'gear77 meshed with 'of which a sprocket 73 is secured upon the,

the gear 7 6 on the shaft 74. In this manner the cross apron isoperated, without requiring special counter shaft and bearing for theconnection.

in use, the machine being operated so that the roller 16 rotates to moveits forward side downwardly, the web 60 passing through the starchprovided in the pan 11 becomes coated therewith before moving into thetable reach and the operator thus is afforded a convenient place uponwhich to arrange the work as it passes into the machine, being able toremove attention from the work after it is once adjusted. By rea son ofthe coating of starch upon the web, the articles are not liable tocasual movement after arrangement upon the table reach, and as the webpasses over the roller as the work will continue to lie clos ly againstthe web until it passes into engagement with the roller 16. The frame 29being properly adjusted, the rollers 32 will work the starch through thepieces carried under the roller 16, and as the web passes between therollers 36 and 38 all surplus starch is removed and the work is carriedby the tapes 62 and web 61 upwardly and over the rollers 53 and 5d, thework having a tendency to cling to the web 61 until loosened by theknife 71 before mentioned, owing to the fact that there is no bend ofgreat degree between the ascending reach, the oblique reach and theinverted reach, The work therefore passes outwardly ever the roller 54-,until engaged by the knife Tl which turns the work downwardly until itstrikes against the cross apron 70, the upper side of which moves towardthe left hand side of the machine. As the end portions of the workstrike against the cross apron after leaving the web 61, the apronpushes these end portions toward the left. The flattened and stiffenedcondition of the work due to the effect of the finishing rollers 36 and3'7 causes it to resist wrinkling or bending, as it is removed from theconveyer 60 by the knife 71, it is caused to curl so that the upper sideof the work leaving the web 50 becomes turned downwardly against theapron 70. The liability of crumpling or wrinkling the work is thusobviated and it is delivered in well ordered form. By having the apronmove at a more rapid rate than the web 61, this effect is enhanced,altl'iough it is not as essential in this form of my machine in theprior construction. It is im portant that enough space he providedbetween the inverted reach and the transverse conveyor, for, if tooclose together, the work will not be ordered and enabled to curl, asdescribed, and it will be crumpled and disordered.

However, it is thought desirable to have the cross apron 7O operate at amuch higher speee than the web 60 in order that as soon as one piece ofwork is cleared from the web 60 entirely, it will be rapidly dischargedat the side of the machine and moved out of the way of other work.

For convenience of the operator, the

frame 10 supports table portion 78 and 79' on a level with its upperedge, at front and rear, the levers 12 and 21 and the pedal 17 beingextended so as to lie in convenient relation to the table 7 8. 4%.receiving table 80 is also provided. at the lett hand side of themachineto receive the work discharged from the cross apron, this table having aplate 81 extended upwardly therefrom. to lie at its upper part closeunder and to the ri 'ht of the outer part of the roller (39, the lone ofthe plate being curved toward the le t, so that the work as dischargedfrom the cross apron will. slide down upon the plate 81 to the table 80without becoming disordered or wrinkled.
